Gradle

dependencies {
    implementation 'com.github.takusemba:spotlight:1.3.3'
}

Usage

Spotlight.with(this)
        .setOverlayColor(ContextCompat.getColor(MainActivity.this, R.color.background)) // background overlay color
        .setDuration(1000L) // duration of Spotlight emerging and disappearing in ms
        .setAnimation(new DecelerateInterpolator(2f)) // animation of Spotlight
        .setTargets(firstTarget, secondTarget, thirdTarget ...) // set targets. see below for more info
        .setClosedOnTouchedOutside(false) // set if target is closed when touched outside
        .setOnSpotlightStartedListener(new OnSpotlightStartedListener() { // callback when Spotlight starts
            @Override
            public void onStarted() {
                Toast.makeText(context, "spotlight is started", Toast.LENGTH_SHORT).show();
            }
        })
        .setOnSpotlightEndedListener(new OnSpotlightEndedListener() { // callback when Spotlight ends
            @Override
            public void onEnded() {
                Toast.makeText(context, "spotlight is ended", Toast.LENGTH_SHORT).show();
            }
        })
        .start(); // start Spotlight

if you want to show Spotlight immediately, use addOnGlobalLayoutListener to wait until views are drawn.

view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override public void onGlobalLayout() {
        view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        Spotlight.with(this)...start();
    }
});

Simple Target

simply set a title and description, these position will be automatically calculated.

SimpleTarget simpleTarget = new SimpleTarget.Builder(this)
    .setPoint(100f, 340f) // position of the Target. setPoint(Point point), setPoint(View view) will work too.
    .setRadius(80f) // radius of the Target
    .setTitle("the title") // title
    .setDescription("the description") // description
    .setOnSpotlightStartedListener(new OnTargetStateChangedListener<SimpleTarget>() {
        @Override
        public void onStarted(SimpleTarget target) {
            // do something
        }
        @Override
        public void onEnded(SimpleTarget target) {
            // do something
        }
    })
    .build();

Custom Target

use your own custom view.

CustomTarget customTarget = new CustomTarget.Builder(this)
    .setPoint(100f, 340f) // position of the Target. setPoint(Point point), setPoint(View view) will work too.
    .setRadius(80f) // radius of the Target
    .setView(view) // custom view
    .setOnSpotlightStartedListener(new OnTargetStateChangedListener<CustomTarget>() {
        @Override
        public void onStarted(CustomTarget target) {
            // do something
        }
        @Override
        public void onEnded(CustomTarget target) {
            // do something
        }
    })
    .build();
